The answer is a because 3/5 equals 0.6
This would be a proportion:
7 4*7
---- , ------- NOTICE THAT 4 IS THE MULTIPLIER IN BOTH CASES
16 4*8
BUT
7 4*7
---- , ------- WOULD NOT BE A PROPORTION. 4 AND 10 ARE DIFFERENT
16 10*8 MULTIPLIERS.
Answer:
- Number of bracelet Jessica can make in 30 minutes=2
- Number of bracelet Jessica can make in 60 minutes=4
- Number of bracelet Jessica can make in 90 minutes=6
- Number of bracelet Jessica can make in 120 minutes=8
- Number of bracelet Jessica can make in 180 minutes=12
Jessica can make <u>12 bracelet</u> in 180 minutes (3 hours).
Step-by-step explanation:
Number of bracelet Jessica can make in 30 minutes=2
Number of bracelet Jessica can make in 180 minutes=(180×2)/30=12
or,
Number of bracelet made by Jessica is directly proportional to the time taken by her.
Number of bracelet made by Jessica=k×time taken by her, where k is a constant
In all cases value of k is 15
Therefore,
Let the number of bracelet be x and putting the value of k, we get
xk=180 minutes (3 hours)
15x=180
x=180/15
x=12
